OAKDALE, Minn. -- A Minnesota high school senior who turned to the porn industry for a prom date found a couple of takers, but school administrators say the X-rated actresses aren't welcome.

Mike Stone says he sent dozens of Twitter messages to Hollywood celebrities, mostly porn actresses, and received a response from two, Megan Piper and Emy Reyes. They agreed to accompany him to the May 12 prom at Tartan High School in Oakdale, a St. Paul suburb.

But Superintendent Patty Phillips says such a date is prohibited by school policy that disallows a visitor if it's not in the best interest of the students.

The 18-year-old Stone says he'll hold an alternative party at the same time as the prom so he can bring his dates.
